摘要
菹草作为冬春季沉水植物,在秋季发芽,冬春生长,夏季衰退腐烂并在植株末端形成鳞枝(也称石芽)繁殖。菹草不但具有较高的营养价值,可作为草食性鱼类的良好天然饵料,而且具有去除水体悬浮物、营养盐、重金属离子和抑制藻类繁殖等生态功能,可应用于水体生态修复工程中。分析了菹草在生态修复应用中存在的问题。
As a winter-spring season submerged plant,Potamogeton crispus germinates in autumn,grows in winter and spring and declines,decomposes and forms turions at the end of the plant for propagation in summer.Potamogeton crispus not only has higher nutrient value,can be used as good natural feed of herbivorous fish,but also has ecological functions of removing water substances,nutritive salt,heavy metal ions and inhibition of algae propagation and can be applied into rehabilitation works of water ecology.The paper analyzed the existing problems of Potamogeton crispus in the application of ecological rehabilitation through the combination of present worsen water pollution and the serious situation of water eutrophication.
